ASP.NET从代码背后设置页面标题

Question

I am creating data driven pages using ASP.NET C# and want to dynamically set the page title using code behind

<%@ Page Title="" Language="C#" MasterPageFile="~/FLMaster.master" AutoEventWireup="true" CodeFile="legal-expenses-insurance-news-item.aspx.cs" Inherits="legal_expenses_insurance_news_legal_expenses_insurance_news_item" %>

I have tried using the separate title tags lower down in the page but this didn't work either. Can anyone advise how to do this.

Answer 1

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace MyApplication
{
    public partial class _Default : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            this.Title = "Title of my page";
        }
    }
}

You can modify the Page title like above from your aspx.cs (the code behind file).

If you want to do this directly in your .aspx file, try this:

<% this.Title = "Some Title" %>

This works if you correctly set your Language = "C#" in your @Page directive, which I see you did.

The Page has a Title property :

protected void Page_Load(object sender, EventArgs e)
{
    this.Title = "Title";
}

Answer 3

You should remove the Title="" from the aspx page. It will override the Title set in your code-behind

<%@ Page Language="C#" MasterPageFile="~/FLMaster.master" AutoEventWireup="true" CodeFile="legal-expenses-insurance-news-item.aspx.cs" Inherits="legal_expenses_insurance_news_legal_expenses_insurance_news_item" %>

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            this.Title = "Title";
        }
    }
    

Answer 4

I know that this is an old thread, but I found that Page.Title couldn't always be overriden, but Page.Header.Title could (mostly)... so my solution for dynamic title tags from the Master codebehind is:

    if (Page.Header != null)
    {
        if (Page.Header.Title == null || !Page.Header.Title.Contains("COMPANYNAME"))
        {
            var otitle = Page.Header.Title;
            if (otitle == null || otitle.Length==0) {
                var textinfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo;
                otitle = textinfo.ToTitleCase(this.Parent.GetType().Name.Replace("_"," ").Replace("aspx",""));
            }
            Page.Header.Title = "COMPANYNAME" + " - " + otitle;
        }
        Page.Header.Title = Page.Header.Title.Replace("COMPANYNAME", Auth.getSetting("companyName"));
    }
